Can sternohyoid muscles (neck area) be treated and relaxed by botox injections?

Q:

Maybe because my skin is very thin the sternohyoid muscles (http://www.healthline.com/human-body-maps/sternohyoid-muscle ) on my neck become very prominent when I speak: they are like two sharp vertical lines in the middle of my neck. I know that the platysma can be relaxed by botox injections but I'm unsure if botox can be injected in these bands as well.

A:

The sternohyoid muscle is one of the strap muscle with special function to pull the hyoid down and aid in speech. It is a long skinny muscle. I would not recommend botox for that.
